  • A Review on Transmission Line Faults Detection

    Short Transmission Lines The overhead transmission lines up to the range of approximately fifty kilo-meters and the voltage of line under (<20kV) are considered to be a part of the short transmission line. Due to the low voltage and smaller length, the capacitance effects are minute enough not to trouble the transmission hence they are neglected.
